Table 3 Effect of opsonisation on internalisation of M. hyopneumoniae (pMHGFP-P97) by porcine alveolar macrophages

From: Mycoplasma hyopneumoniae evades phagocytic uptake by porcine alveolar macrophages in vitro

Serum Average number of intracellular M. hyopneumoniae (pMHGFP-P97)
Preimmune 3 ± 0.5 (36 PAMs)
A 3 ± 0.8 (24 PAMs)
B 3 ± 0.5 (24 PAMs)
C 3 ± 0.3 (38 PAMs)
Heat-inactivated foetal bovine 2 ± 0.4 (35 PAMs)
  1. Standard error of the mean ± is shown, the number of porcine alveolar macrophages (PAMs) analysed is shown in parentheses. Sera A, B and C are convalescent M. hyopneumoniae serum, heat inactivated bovine serum served as the control.
